如何從UIAutomator運行「adb命令」

Question

因此，我有一個UIAutomator測試腳本，在執行測試期間我希望它運行一些adb命令。我該怎麼做呢 ？

我在想有沒有辦法在UI automator類中調用腳本？或者有沒有辦法直接執行「adb命令」？

這是我的代碼：

package com.uia.example.my; 


import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStreamReader; 

import com.android.uiautomator.core.UiObjectNotFoundException; 
import com.android.uiautomator.testrunner.UiAutomatorTestCase; 

public class ADBCommandTest extends UiAutomatorTestCase{ 
    public void testDemo() throws UiObjectNotFoundException{ 

     System.out.println("Entering the shell script"); 
     try { 
      ProcessBuilder pb = new ProcessBuilder("./run.sh"); 
      Process p = pb.start(); 
      BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream())); 
      String line = null; 
       while ((line = reader.readLine()) != null) 
       { 
        System.out.println(line); 
       } 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

    } 

} 

這是錯誤我得到：

我把run.sh腳本文件在我的類文件是同一個地方。請幫忙。

Answer 1

以下是可用的代碼。在運行UiAutomator測試之前，我已將腳本文件「command.sh」複製到外部SD卡。

該代碼不需要任何root權限。

package ui; 
import java.io.File; 
import java.io.IOException; 
import android.os.RemoteException; 
import com.android.uiautomator.core.UiDevice; 
import com.android.uiautomator.core.UiObjectNotFoundException; 
import com.android.uiautomator.testrunner.UiAutomatorTestCase; 

public class SampleCode extends UiAutomatorTestCase { 
    public void testHome() throws RemoteException, 
     UiObjectNotFoundException { 

    // press Home 
    UiDevice mydevice = getUiDevice(); 
    if (!mydevice.isScreenOn()) { 
     mydevice.wakeUp(); 
    } 
    mydevice.pressHome(); 

    // Script path 
    String filePath = "/mnt/sdcard_ext/command.sh"; 
    File command = new File(filePath); 
    command.setExecutable(true); 

    // Run command 
    Process p = null;  
    try { 
     Runtime.getRuntime().exec(
       "/system/bin/sh /mnt/sdcard_ext/command.sh"); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally { 
     if (p != null) 
      p.destroy(); 
    } 

} 

}

這裏是 「command.sh」 的內容，輸出將被寫入到文件上的外部SD卡

SDCARD="/mnt/sdcard_ext/" 
LOG="$SDCARD/testlog.txt" 
logcat -d >> $LOG 

Answer 2

試試這個方法 -

public String shell(String cmd) { 

    String s = null; 
    try { 
     Process p = Runtime.getRuntime().exec(cmd); 

     BufferedReader stdInput = new BufferedReader(new InputStreamReader(
       p.getInputStream())); 

     BufferedReader stdError = new BufferedReader(new InputStreamReader(
       p.getErrorStream())); 

     // read the output from the cmd 
     String result = ""; 
     while ((s = stdInput.readLine()) != null) { 
      result = result + s + "\n"; 
     } 

     // read any errors from the attempted comd 
     while ((s = stdError.readLine()) != null) { 
      System.out.println(s); 
     } 
     return result; 

    } catch (IOException e) { 
     System.out.println("exception here's what I know: "); 
     e.printStackTrace(); 
     return "Exception occurred"; 
    } 
} 

現在撥打電話

String ls= Shell("ls");

我以前用於使用運行時方法在測試setUp（）/ tearDown（）中注入shell命令，但當我切換到UIAutomator 2.0和Gradle時，它停止工作。

如果你細使用API​​ 21（棒棒糖）及以上的，谷歌提供這個API我們：

InstrumentationRegistry.getInstrumentation().getUiAutomation().executeShellCommand("pm clear " + Constants.PACKAGE_NAME); 

這個方法對我的作品。來源：
